Question:
Boric acid, B(OH)3, is used as a mild antiseptic. What is the pH of a 0.015 M aqueous solution of boric acid? What is the degree of ionization of boric acid in this solution? The hydronium ion arises principally from the reaction
B(OH)3(aq) + 2H2O(l) ⇌ B(OH)4−(aq) + H3O+(aq)
The equilibrium constant for this reaction is 5.9 × 10-10.
